Skip Montanaro 2c0d3224fc tightened up the definition of \b and \B some more based upon discussion

Fred Drake 5b11bdd0ed SF patch #581414: info reader bug 
The "Matching vs. Searching" Info node is unreachable from the Info
program (but is fine in Emacs's Info mode). This patch seems to fix
it.  This is the only occurrence where the info reader fails, so
probably it could be addressed in the python docs as a workaround.
Forwarded the report to the info maintainer.

Fred Drake 9479c958c5 Remove extra indenatation from sample interpreter session. 
Remove whitespace from the middle of an inline RE example; it was OK for
the typeset formats, but LaTeX2HTML is more touchy about this.
 2002-03-05 04:02:39 +00:00

Andrew M. Kuchling 1f774b062e Update obsolete e-mail address, and remove myself as a module author 2001-11-05 21:34:36 +00:00
Tim Peters 7533587d43 Improved error msg when a symbolic group name is redefined. Added docs 
and NEWS.  Bugfix candidate?  That's a dilemma for Anthony <wink>:  /F
did fix a longstanding bug here, but the fix can cause code to raise an
exception that previously worked by accident.
 2001-11-03 19:35:43 +00:00
Fred Drake 0aa811c527 Use the \note and \warning macros where appropriate. 2001-10-20 04:24:09 +00:00
Tim Peters 9835206268 A regexp example was rendered as 
foo\d
when it was clearly intended to render as
    foo$
Fred, is this a right way to fix it?  If not, the earlier place in the
same paragraph that does render as
    foo$
is also wrong.
 2001-10-05 20:06:47 +00:00
Eric S. Raymond 46ccd1dae5 Plant a mention in the description of backreferences of the fact that 
while \0 doesn't do what one might expect, \g<0> does.
 2001-08-28 12:50:03 +00:00
Fred Drake 51629c245a Add a caveat about boundary conditions and RE concatenation, so that the 
documents do not make an overly-strong assertion about the properties of
RE concatenation.

Add an example of RE{m,} syntax and what it will and will not match.
 2001-08-02 20:52:00 +00:00
Fred Drake e74f8de385 Added an example of a string value for the replacement parameter to 
re.sub().
This closes SF bug #446136.

Fixed description of RE modifiers so that RE{#} and RE{#,} are more
clearly described and disambiguated (plain RE{#} had not been described
at all).  Reported by Jeremy Craven via email.
 2001-08-01 16:56:51 +00:00
Fred Drake c547b46c06 Be more specific about corner cases in the description of the $ RE syntax,

matched; reported by Paul Moore.

Wrapped several long lines.
 2001-07-12 14:13:43 +00:00
Fred Drake 907e76b620 Fix up a few style nits -- avoid "e.g." and "i.e." -- these make 
translation more difficult, as well as reading the English more
difficult for non-native speakers.
 2001-07-06 20:30:11 +00:00
Fred Drake 895aa9da4c Suggestion from Keith Briggs: refer to RE objects consistently instead of 
introducing a new term ("regex") without defining it.
 2001-04-18 17:26:20 +00:00
Fred Drake e20bd19f86 Convert several \seetext references to \seerfc and \seetitle versions.

Fred Drake 062ea2e70b Made a number of revisions suggested by Fredrik Lundh.

when 7-bit strings were assumed; note that Unicode strings can be used.
